Design of Discrete-time Matrix All-Pass Filters Using Subspace Nevanlinna Pick Interpolation
Agulla Surya Bharath, Devanshu Singh Gaharwar, Kumar Appaiah +1
Unitary matrix-valued functions of frequency are matrix all-pass systems, since they preserve the norm of the input vector signals. Typically, such systems are represented and anal…
